Over the weekend at Come Hell or High Water in Atlanta, Georgia, Cody Rhodes & The Young Bucks made a surprise appearance. After the main event between Pentagon Jr. & Fenix vs. Christopher Daniels & Frankie Kazarian, Nick & Matt Jackson made their way out and invited Pentagon Jr. & Fenix to wrestle for AEW.
It is likely that Pentagon Jr. & Fenix will be appearing at AEW Double Or Nothing on May 25th in Vegas at The MGM Grand Garden Arena.

Just recently, MLW CEO Court Bauer thanked Pentagon Jr. & Fenix for their time in MLW, reigning as The Tag Team Champions for over seven months. Bauer continued, “Wherever you go next always know you both are 1000000000% leyendas de Lucha Libre!” so it looks like the duo is finished up with MLW.

I want to thank @PENTAELZEROM @ReyFenixMx for an extraordinary 7+ months as the @MLW World Tag Team Champions. Mas chingons! MLW will always embrace you as family as you helped build this house. Wherever you go next always know you both are 1000000000% leyendas de Lucha Libre!

According to Lucha Central, the deal with AEW was not exclusive as the duo currently works for AAA, CMLL, IMPACT & Lucha Underground (if a fifth season is filmed).

Although the timing of Pentagon Jr. & Fenix finishing up with MLW is curious, it may just be a coincidence. Both have multiple dates still in Mexico and were at the most recent tapings for IMPACT Wrestling.
